The campaign blog said that it hopes the 'Call Friends' feature will generate thousands of additional personal contacts - the aim being that these can be turned into votes. Other features include making notes on which friends have been called, who they are supporting, and if they need a reminder call on election day. Up-to-date news from the campaign will also be included, as will video, photos and talking points that can be used to convince friends to vote for the candidate.

The website said the total amount of calls the application makes are tallied but no information leaves the phone, so the privacy of friends and that of the user are protected.
